Recently, the concept of mechanical finalization of the biomechanical preparation was proposed.
Following the biomechanical preparation, the canals were irrigated, flushed with EDTA 17%, and dried prior to obturation.
2.5% sodium hypochlorite (NaOCl) solution was used as the main irrigant during biomechanical preparation. Root canal filling was completed by using the cold lateral compaction method with AH Plus (Dentsply DeTrey, Konstanz, Germany) sealer and gutta-percha (Diadent Group International, Chungcheongbuk-do, Korea).
Endodontic therapy primarily aims at the elimination of microbes and tissue debris from the infected root canals by thorough biomechanical preparation followed by three-dimensional obturation with a hermetic seal to prevent further reinfection.
The traditional concepts of root canal preparation, biomechanical preparation, chemomechanical preparation, or cleaning and shaping have been known for decades.
In the first appointment Biomechanical preparation of the canals were performed and the canals were dressed with calcium hydroxide paste before sealing the access cavity with a temporary restorative material.
After the contamination period, the instrumentation from size 40 K file up to size 50 K file was performed to verify the antimicrobial action of irrigants in combination with biomechanical preparation, thus stimulating the clinical situation.
Biomechanical preparation was done with combined rotary nickel titanium protaper universal and hand instrumentation using crown down technique.
This paved the way for a more cleaner, thorough and faster biomechanical preparation of the root canal system.
Postponement of final obturation with gutta-percha after initial extraoral biomechanical preparation serves in performing better obturation and delaying root resorption.
After the biomechanical preparation the root canals were dressed with calcium hydroxide paste and the access cavity was filled with a temporary restorative material.
Disinfection of the root canal is obtained by the combined effect of biomechanical preparation, irrigation and intra canal medicament [6,7].
